It's not just you. Imgur has the most craptastic UX of all the super-popular web apps I've seen. Aside from Ctrl+V to upload, I can never find my easily through their interface. Really, really terrible. Don't know how those guys got so famous and raised $40M with such shitty usability.

A Select images for this album pop-up then appears. The boxes on the left allow to add images that are not in albums, or all images.
So click on Non-album images, select the ones you want moved into the selected album, then click Save.
